Generic GPU fence class. Granularity differs depending on backing RHI - ie it may only represent command buffer granularity. RHI specific fences derive from this to implement real GPU->CPU fencing. The default implementation always returns false for Poll until the next frame from the frame the fence was inserted because not all APIs have a GPU/CPU sync object, we need to fake it.
